BESPIRATORS, AND THE Application filed December 1'7, 1925, Serial No.75,907, and in Germany December 24, 1824.

The present invention relates to. a system of straps to hold arespirating device such as a respirator, a mask, a breathingdevice orsimilar appliances to the head of a human body. The object of theinvention is to provide a structure of straps of this kind, whichhereinafter is called a harness, that can be very readily andeconomically made, the harness being exceedingly simple and economic ofconstruction and capable of being expeditiously and conveniently appliedor removed. Another object of the invention is to provide a harness ofthis kind that will maintain the respirating appliance in place on theface in proper position, but will not cause discomfort to the wearer,irrespective of. the shape of the head.

The invention consists in the novel construction and combination of theseveral" 2 parts as will be hereinafter fully set forth and pointed outin the claims.

Reference is to be had .to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Fig. 1 is a perspective view of a harness in connection with a mask,

Figs. 2, 3 and 4 are modifications 'of the harness shown in Fig. 1, and

Fig. 5 is a perspective view of a harness in connection with arespirator.

In the construction shown in Fig. 1 the harness, which is supposed to beused in connection with a mask a, comprises a pad or fiat member I) anda certain number of straps hereinafter more fully described. By a slipconnection the pad I) is engaged atv its lower end by a nape strap aconnected at its ends with the two sides of the mask a. The slipconnection consists of a loop d through which the nape strap 0 passes,and which is attached to the pad b by any suitable means. From the upperend of the pad 1) extends a top strap 6 the forward end of which isconnected with a mask a by two transversal straps If found convenient afront strap 9 may be provided to form a prolongation of the top strap 6,and if desired further horizontal transversal straps k may be used toconnect the pad b with the sides of the mask, so as to give the pad agreater steadiness. Of course buckles i may be used as usual in similarstructures for securing the necessary adjustability.

In the construction shown in Fig. 2 the front strap is bifurcated thevtwo branches being made integral with the transversal straps to formprolongations thereof.- To connect the strap 6, the transversal straps fand the bifurcated front stra g in this figure a slotted member forme bya plate m is shown having diagonal slots n, through which the straps f,9 pass thus forming a 3111i connection.

In. the construction shown in Fig. 3 the two parts of the bifurcatedfront strap are made of one; continuous tape or belt passing through.the slot of a second slotted member of attachment 0, thus the combinedor continuous front and lateral strap passes through the two members ofattachment m and 0 following the lines of an M. It is evident that bythese means great convcnience will be given to the wearer. Instead of 75making use of bucklm, or in addition thereto, parts p of the variousstraps may be made elastic as indicated.

The construction shown in Fig. 4 differs from those described above inas much as the slip connection between the nape strap and the pad 6consists of two loops d instead of one. These two loops are attached tothe pad at a certain distance from one another to avoid inconvenientpressure on the sensitive part of the nape.

In the. construction shown in Fig. 5 the two loops d attached to the padI) has the effect to protect in a similar manner the sensitive part ofthe nape from disagreeable pressure. In this construction, in which theharness is applied to a respirator or mouthbreathing appliance, the adis made in one with the top strap, the ront end of which is connectedwith the transversal straps by a ring.

I claim 1. A harness for respirating appliances such as masks,respirators and the like, comprising a pad arranged to lie at the backof the head, a center top strap attached to the upper end of the pad andextending forwardly therefrom and adapted to lie on top of the head, twotransversal straps connected with the sides of the respiratingappliance, slip connections between said transversal er end of said padand the sides of said res-- pirating appliance.

2. A harness for respirating appliances such as masks, respirators andthe like,

comprising a pad arranged to lie at the back of the head, a center topstrap attached to the upper end ofthe pad and extending forwardlytherefrom and adapted to lie on top of the head, two transversal strapsconnected with the sides of the respirating appliance, a plate havingdiagonal slots attached to the center strap, a bifurcated front strapmade in one with the two transversal straps and passing through thediagonal slots of said plate to form a slip connection between saidcenter top strap, said transversal straps and said bifurcated frontstrap, and strap connections between the lower end of said pad and thesides of said respirating appliance.

3. A harness for respirating appliances such as masks, respirators andthe like, comprising a pad arranged to he at the back of the head, acenter top strap attached to the upper end of the pad and extendingforwardly therefrom and adapted to lie on top of the head, twotransversal straps connected with the sides of the respiratingappliance, slip connections between said transversal straps and thefront end of said center top strap, a nape strap extending continuouslyfrom one sideof the respirating apparatus to the other and having itsopposite ends attached to the two sides of said respirating apparatus,and a slip connection between said pad and said nape strap.

4. A harness for respirating appliancessuch as masks, respirators andthe like, comprising a pad aranged to lie at the back of the head, acenter top member extending forwardly from the upper end of said pad andadapted to lie on top of the head, a slotted member attached to saidcenter top strap, a second slotted member attached to said respiratingappliance, and a combined front strap and two transversal strapsconnected at thein opposite ends with said respirating appliance andslidably passing through said slotted members whereby said combinedtransversal straps and front strap form a strap slidably connected withsaid center front strap and appliance.

5. A harness for respirating appliances, comprising a fiat memberarranged to lie at the back of the head, a slotted member, a center topmember extending from said fiat member to said slotted member andadapted to lie on top of the head, a combined front strap and twotransversal straps connected at at least three points to the respiratingappliance and slidably passing through said slotted member, whereby saidcombined front strap and transversal straps form a member slidablyconnected with said center front strap, a nape strap extending from oneside of the respirating appliance to the other and having its endsattached to the sides of the respirating appliance, and a slipconnection between the lower end of said fiat member and said napestrap.

In testimony whereof I have signed my name to this specification.

ALEXANDER BERNHARD DRKGER.
